Title: Variable-speed gearbox
IPC: F16H47/08
Filed: 1979-05-04
Abstract: In order to minimise the number of major components relative to the number of speed ratios available in an epicyclic gearbox downstream of a hydrodynamic torque converter the gearing includes an annular gear 20 capable of being held against rotation by a brake 28 so as to constitute a reaction member when every one of the reverse speed ratios (four in the construction shown) is engaged and alternatively capable of transmitting drive when at least some of the forward speed ratios (five in the construction shown) are required. Furthermore, the gearbox is so constructed that only one clutch or brake need be de-actuated and one other clutch or brake simultaneously actuated in its place for every change of forward speed ratio, in order promptly to effect any such change. The gearbox is particularly intended for heavy duty wheeled or tracked land vehicles. <IMAGE>

Patent GB-2026367-A (GB)
Title: A connection method for joining parts
IPC: B23P11/00
Filed: 1979-07-25
Abstract: A connection method for joining parts by means of a connecting element, e.g. a rivet or screw, passing through a hole in each of the parts involves precoating the element with a sealing or corrosion inhibiting material of liquid or paste form and storing the element in a cooled state so as to retard hardening until required for use. The parts are then joined by the connecting element and the sealing or corrosion inhibiting material is allowed to harden. The method is particularly suitable for large scale production processes in which large quantities of coated connecting elements can be stored in a cooled state ready for use. The risk of contaminated fastening tools or over-hardened coating materials is reduced.

Title: Repair of beer kegs and containers
IPC: B21D51/20
Filed: 1981-05-14
Abstract: In the repair of an overblown beer keg the end chime rings (9 and 10) are first removed and, if damaged, subsequently repaired or replaced as may be necessary. The remaining container portion of the keg is cut centrally into two equal parts (1 and 2). Each part (1 or 2) is fitted on an expander which is operative to apply a substantially even and radially outward pressure (in direction of arrows 5) to an end region of the side wall (6) of the part (1 or 2) where that wall joins the domed end (3) of the part. This pulls in the outwardly deformed domed end (3) to a position beyond that corresponding to its original shape, and thus over compensates for the overblown condition. The end (3) is then embossed on its inner face with a star-shaped embossing tool, the depth of embossing compensating for the over compensation of the pulling-in procedure and thus restoring the container volume to its correct volume. After any necessary reshaping, the expanded and reformed end parts (1 and 2) are welded back together to provide a repaired and strengthened container. The chime rings (9 and 10) are then replaced to complete the keg repair. <IMAGE>
